rotor agilis xc2
first impression with the crankset is very very good. it looks very carefully built with high attention to detail! the chainrings are absolutely impressive, everything is cnc machined.
i opted for the agilis xc2 mainly because of it's rigidity. they have a special cnc operation where they cut the crankarms outside aswell as inside! yep cnc inside the arms! they go through this very complicated cnc process because they say that the rigidity is 30% higher at the same weight!
forged aluminum loses some of the strength properties compared to the cold cnc machined one !
the chainrings are q-rings, which means they are oval and are adjustable. adjustable in the sense that you can set them to behave differently . i installed them on position 2 , later to have them moved to 3! there is an accommodation period with these chainrings and they suggest you start with position 2!
the xc2 is two chainrings only and because of they're shape they come in 40/27 t . i've noticed that as well with 29'er bikes, that the mtb direction is towards 2 chainrings and not 3. a little bit of inspiration from road bikes now with the release of sram's 10spd mtb casette?!
also a special part of the crankset are the bb's. because i wanted to have the bb's for 68mm without spacers, the guys from velotechservices sent me 2 bb's one sabb and the bb1, a nice gift from a bunch of nice chaps!
the bb1 is a 100gr light bb designed for mtb use with spacers for 68mm shell
the self alignment bottom bracket is what it's name says...the picture explains everything!
they claim a weight of 753 grams including bottom brackets, chainrings, spacer etc but my scale shows only 720...
hope mini x2 pro
well...evryone knows how hope brakes feel and how they brake but the x2 is a step higher than my m4 and m6! i have to honestly say it that i ahave always been a huge fan of this small company called hope and they have not let me down with the x2 pro!
620gr with 160mm rotors, i think it's pretty fair!
